Lifting system

Abstract

A lifting system comprises a platform ( 10 ) with at least one inflatable body ( 21, 22 ) which is connected to a fluid conduit ( 23, 24 ) for the purpose of receiving an inflating fluid, particularly a gas under increased pressure such as compressed air. In a first aspect the at least one inflatable body ( 21, 22 ) is connected for rotation about a rotation axis (H) relative to the platform ( 10 ). The inflatable body ( 21, 22 ) bounds here a winding space ( 40 ) in which the fluid conduit, when not in use, is received in a state in which it is wound around the rotation axis. In a second aspect the lifting system comprises on or at the platform ( 10 ) a fluid system ( 51, 52 ) which is remotely controllable.

The invention claimed is: 
     
         1 . A lifting system, comprising a platform and at least one inflatable body, wherein the at least one inflatable body is connected to a fluid conduit for the purpose of receiving an inflating fluid, particularly a gas under increased pressure such as compressed air, wherein the at least one inflatable body is connected for rotation about a rotation axis to the platform, and wherein the at least one inflatable body bounds a winding space in which the fluid conduit, when not in use, is wound around the rotation axis. 
     
     
         2 . The lifting system according to  claim 1 , wherein the at least one inflatable body comprises an inflatable cushion which is connected rigidly to a central shaft, and wherein the central shaft extends from the platform rotatably about a central axis of the at least one inflatable body. 
     
     
         3 . The lifting system according to  claim 1 , wherein the at least one inflatable body comprises a stack of a first inflatable body and a second inflatable body, and wherein the first inflatable body and the second inflatable body bound the winding space therebetween and are both connected for rotation about the rotation axis to the platform. 
     
     
         4 . A lifting system, comprising a platform with at least one inflatable body which is connected to a fluid conduit for the purpose of receiving an inflating fluid, particularly a gas under increased pressure such as compressed air, wherein the fluid conduit connects the inflatable body to a fluid reservoir via electronically controllable valve means, wherein the valve means are coupled to an electronic control device and are controllable thereby, wherein an operating device is coupled to the control device in order to enable a user to operate the control device, and wherein the operating device is coupled wirelessly to the control device. 
     
     
         5 . The lifting system according to  claim 4 , wherein at least one fluid reservoir, the valve means and the control device are connected optionally directly to the platform together with the at least one inflatable body. 
     
     
         6 . The lifting system according to  claim 4 , wherein the valve means comprise at least one of an electronic proportionally controllable pressure reducing valve and an electronic control valve. 
     
     
         7 . The lifting system according to  claim 1 , wherein the platform comprises a rolling and/or sliding platform. 
     
     
         8 . The lifting system according to  claim 1 , wherein the platform is coupled to a shaft, wherein the shaft provides a handle at a proximal outer end, and wherein the shaft features a control device and/or operating device for a fluid reservoir as well as the fluid reservoir and that said fluid conduit is connected to the fluid reservoir. 
     
     
         9 . The lifting system according to  claim 8 , wherein the shaft is coupled to the platform in manually releasable manner. 
     
     
         10 . The lifting system according to  claim 8 , wherein the shaft is coupled to the platform for pivoting about a pivot axis and can be folded together with the platform with the at least one inflatable body.
